ROVlNG-GUIDE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 600,236, dated March 8, 1898.

Application led November 2l, 1896. Serial No. 612,934. (No model.)

To a/ZZ whom. t may concern:

Be it known that I, ISAAC H. RUSSELL, a citizen of the United States, and a resident of Fall River, county of Bristol, and State of Massachusetts, have invented certain new and useful Improvements in Roving-Guides for Spinning-Machines, of which the following is a specication.

My invention relates to that class of mechanism for the manufacture of yarns in which trumpets or condensers are arranged between the successive pairs of drawing-rolls to gather into the body of the material passing between them the outlying or projecting fibers, as well as in rear of the first or entry pair of such rolls, to conduct the said material thereto, and especially to that form thereof in which these trumpets or condensers are arranged between the last two pairs of drawing-rolls to act upon the material in its most attenuated state, as shown, for instance, in Letters Patent of the United States No. 317,67 5, which were granted to The Abbot Spinner Company as my assignee May 12, 1895, to which reference may be had.

In mechanism of this class, as heretofore constructed, it has been the custom to impart to the trumpets or condensers placed in rear of the first or entry pair of drawing-rolls a bak-and-forth traversing movement along the same, whereby, while permitting of the free and unobstructed delivery of the material thereto, to cause the various points at which such delivery is made to traverse back and forth along the said rolls and thereby distribute the wear incident to its passage along their peripheries to a greater or lesser extent, while the trumpets or condensers placed between the pairs of drawing-rolls have been so mounted as not to partake of that movement. The trumpets or condensers in rear of the first or entry pair of drawing-rolls being thus traversed back and forth along the latter, while their respective cooperating trumpets or condensers between the pairs of drawingrolls are stationary, are not, as is obvious, maintained at all times with their individual cooperating members in iixed lines transversely of the drawing-rolls, but are carried rst to one side and then to the other thereof, and the material delivered by them and passing between the successive pairs of rolls and through the stationary trumpets or condensers, instead of traveling at right angles to the axes of these rolls, as is its normal tendency, is caused to approach the stationary trumpets or condensers and pass between the rolls in front of them in lines more or less oblique to their axes, except when such movable trumpets or condensers are brought into positions midway the extreme limits of their traversing movement. As a result of this the material in passing between the drawingrolls, instead of traveling freely through the stationary trumpet-s or condensers at all times with the minimum degree of friction or rei straint, is either subject to an excessive strain or inordinate chafing action or else leaves such trumpets or condensersentirely, especially when the movable trumpets orcondensers are at or near the limit of their traversing movement in one or the otherdirection.

To obviate the objections thus pointed out and insure the maximum degree of efficiency of operation of the trumpets or condensers both between the pairs of drawing-rolls andV in rear of the first or entry pairn thereof are the objects of my invention; and to this end the invention consists, first, in so combining the trumpets or condensers between the successive pairs of drawing-rolls, with the trumpets or condensers in rear of the first or entry pair thereof, that the two shall traverse back and forth in unison and maintain the corresponding ones of the two series at all times in lines at substantially right angles to the axes of such rolls, and, second, in various other subsidiary combinations and constructions of parts,ali as willhereinafter more fully appear.

Referring to the accompanying drawings, which form part of this specication, Figure 1 is a plan view of a section of the drawingrolls of a spinning or roving frame, showing also the finger-bars for maintaining the top rolls in proper positions over theircompanion bottom rolls, the trumpets or condensers between the pairs of drawing-rolls and in rear of the front or entry pair thereof, with the means made use of for traversing these trump- IOO ets or condensers constructed in accordance with my invention and with the middle set of top rolls removed 5 Fig. 2, a rear elevation thereof, portions of the iin ger -bars being broken away for convenience of illustration; Fig. 3, a transverse section of the same, taken in the plane ne of Fig. 2; Figs. and 5, plan f views, respectively, of the two members of the connecting devices intermediate the trumpets or condensers between the pairs of drawing-rolls and the trumpets or condensers in rear of the irst or entry pair thereof; Figs. 6 and 7, front and rear elevations, respectively, of one of the trumpets or condensers employed between the pairs of drawing-rolls; and Fig. 8, a diagram to be hereinafter referred to.

In all the figures like letters and numerals of reference are employed to designate corresponding parts.

A A A2 and a a a2 indicate the bottom and top rolls, respectively, of a` spinning or roving frame, and B and B the trumpets or condensers arranged intermediate the pairs of drawing-rolls and in rear of'the first or entry pair thereof, respectively. `In the drawings I have shown but three pairs of these drawing-rolls, with the intermediate trumpets or condensers B employed only between the middle and the front or delivery pairs; but this is unessential, and the number ot' pairs of rolls may be increased or diminished and the trumpets or condensers employed between any other of the pairs thereof, as may be desired.

The bottom rolls A A A2 are supported in suitable bearings in the stands C, which are preferably constructed with the adjustable portions c and c', that are respectively provided with the bearings for the rolls A' A2, whereby to permit of the adjustment of the distance between such rolls to adapt the frame to the working of fibers of different lengths, while the top rolls a ce a2 are mounted in the finger-bars D, which are journaled at their ends in the portion c of the stands C and likewise constructed with adjustable portions (Z and d, whereby to permit of the adjustment-of the bearings of the rolls a and a2, which are respectively formed therein to accommodate such rolls to the adjustment of their companion under rolls A and A2, respectively. As thus arranged the several pairs ot' the rolls are rotated at the proper relative speeds to effect the required draft of material passing between them by the train of gears that is usually employed for that purpose.

E indicates the traverse-rod,which receives and carries the trumpets or condensers B', and E the rod to which the trumpets or condensers B are secured. These'rods respectively rest in suitable bearings c and e', formed in the stands C, and the former islongitudinally reciprocated to impart the required traverse motion back and forth to the trumpets or condensers B' from the cam F,

vin the stand Gr and rotated from the roll A2 with a bar K, that in turn is secured by a screw 7c to said rod. By this means, as will be seen, when the cam F is rotated the traverse-rod E through the lever I will be reciprocated and the required back-and-forth traversing movement along the rolls thereby imparted to the trumpets or condensers E.

The construction and arrangement of parts as thus far described possess no novelty in themselves, but are or may be the same as those heretofore employed and require no further description herein.

With the parts organized as above eX- plained, however, the material in passing between the drawing-rolls, instead of traveling in lines at right angles to the axes of the latter at all times, as is its tendency, is, in consequence of the traversing movement of the trumpets or condensers E, caused to approach the stationary trumpets or condensers E and pass between the rolls of the pairs A a and A2 a2 in lines more or less oblique to their axes except when such former trumpets or condensers occupy positions midway their eX- treme limits of movement, as shown more clearly in Fig. 8, wherein a* uit* 6*2* indicate the axes of the drawing-rolls, l:k the line of travel of the material when passing them at right angles, as when the movable trumpets or condensers are in positions midway their limits of movement, and 1** its line of travel when obliq ue thereto, as when such trumpets or condensers are on either side thereof. With the material approaching the stationary trumpets or condensers B from the traversing trumpets or condensers B' obliquely to the axes of the pairs of rolls A a. and A2 a2 and leaving them in paths at right angles to the axes of the pair of rolls A a a bend is made therein around the delivery ends of the stationary trumpets or condensers B, and as a consequence thereof more or less friction is occasioned thereto. Further than this, when such bend in the material at these points is great, as when the trumpets or condensers are vnear the limit of their traversing movement in one or the other direction, the material not infrequently passes up over thewalls of the stationary trumpets or condensers B, and leaves the trumpets or condensers entirely. To obviate these obj ections,I cause the trump` ets or condensers B to traverse back and forth in unison with the trumpets or condensers B', whereby to maintain the individual coperating members B B of the two at all times in lines that are approximately at right angles to the axes of the drawing-rolls notwithstanding their traversing movements. To cause IOO IIO

this traversing movement of the trumpets or condensers B in unison with the trumpets or condensers B', various means may be employed. I prefer, however, to effect such movement from the traverse-rod E, and for this purpose I iind it convenient to connect the rod E, to which they are secured, thereto. The means whereby this connection is accomplished may be modified in various ways, it

only being essential that, whatever its form, it be so devised as to cause the reciprocation of the rod Ein unison with the traverse-rod E'. The form, however, selected by me forthe illustration of my invention consists of the two'members N and O, which are secured together by a bolt n, and each is provided with an upturned outer end 0, which is secured by a screw 2J to the rods E or E respectively. As thus arranged any longitudinal traversing movement imparted to the traverse-rod E will, as is obvious, be communicated to the rod E, and in order to permit of the adjustment of these rods to greater or lesser distances apart in consequence of a like adjustment of the d rawi'ng-rolls I provide one of such members-as, for instance, O-with a groove q in its upper side and the other-asfor instance, N-with a correspondingly-shaped tongue o' for engagement with the groove q, whereby to form a tongueandgroove connection between them and likewise elongate the orifice s, through which the bolt n passes into a slot, to the end that the members N and O may slide upon each other and their united length be made longer or shorter, as required.

With the parts constructed as above described any of the well-known forms of trump ets or condensers may be employed between the pairs of drawing-rolls. I prefer, however, to construct them with bottoms l), which ineline forwardly and upwardly from their respective supporting-shanks h to their forward ends, and are severally provided along their converging edges with narrow upwardly-extending walls b2, which similarly converge from their rear to their front ends and have their upper edges rounded oft in a flattened curvilinear form that gradually merges at its front and rear endsin the front and rear ends, respectively, of the bot-toms b, as shown more clearly in Figs. 6 and 7. As thus constructed, these trumpets or condensers are fixedly secured to the rod E by screws or otherwise, so as to traverse with it as it in turn is reciprocated back and forth from the traverserod E', and by their peculiar construction and the form of their walls they not only serve to condense the material passing between the drawing-rolls, but also permit of the same passing over their walls and into their interiors when from any cause it may have become removed from the latter.

From the foregoing it will thus be seen that by my improvements I not only avail of the advantages due to the employment of trumpets or condensers between the pairs of drawingrolls and to the traverse of the trumplast-mentioned trumpets or condensers at all' times.

Although in the foregoing I have described the best means contemplated by me for carrying my invention into effect, I wish it distinctly understood that I do not limit myself strictly thereto, but reserve to myself the right to modify the same in various ways without departing from the spirit thereof.

I may here remark that in referring herein to the front7 and rear of the drawingrolls and the parts cooperating therewith I have considered the side where the material is discharged from the drawing-roll as the front, and the side at which it enters them as the rear.

Having now described my inventionand specified certain of the ways in which it is or may be carried into effect, I claim*- l. The combination, lwith the trumpets or condensers arranged in rear of the irst or entry pair of drawing-rolls, and trumpets or condensers arranged intermediate the pairs of drawing-rolls, of mechanism for imparting to both sets of trumpets or condensers a baelr-and-forth traversing movement in unison, substantially as described.

The combination, with the trumpets or condensers arranged in rear of the entry pair of drawing-rolls, the traverse-rod upon which these trumpets or condensers are mounted, and the means whereby the traverse-rod is re ciprocated back and forth along the drawingrolls, of trumpets or condensers arranged intermediate the pairs of drawing-rolls, a rod to which these last-mentioned trumpets or condensers are secured, and mechanism for connecting this rod to the traverse-rod Whereby to cause the two rods to reciprocate back and forth in unison, substantially as described. Y

3. The combination, with the trumpets or condensers arranged in rear of the entry pair of drawingrolls, the traverse-rod upon which they are mounted, and mechanism for reci procating this traverse rod back and forth along the drawing-rolls, of trumpets or condensers arranged between successive pairs of drawingrolls, a rod to which these last-men tioned trumpets or condensers are secured, a connecting device, composed of two members adjustably secured together and iixedly attached at one of its ends to the rod which supports the trumpets or condensers between the successive pairs of drawing-rolls, and at its other end attached to the traverse-rod in rear of the entry pair of drawing-rolls, substantially as described.

4. The combination, with the trumpets or condensers arranged in rear of the first or entry pair of drawing-rolls, of trumpets or IOO IIO

In testimony whereof I have hereunto set my hand this 10th day of November, 1896.
